The Arts and Crafts movement challenged Victorian taste and style, was inspired by social reformers of the time and espoused the notion of good design being linked to notions of a good society.
According to Wikipedia:
The Arts and Crafts movement was an international movement in the decorative and fine arts that began in Britain and flourished in Europe and North America between about 1880 and 1920, emerging in Japan in the 1920s.
